Fibo 850 super lightweight concrete blocks are suitable for general-purpose walling applications. They provide a good base for plasters, renders and fixings, and the 100 mm option combines easy handling with great thermal efficiency values.

They are also Category 1 masonry units manufactured under a BSI-certified Quality Management System, which is BS EN 9001 compliant.

Manufactured to BS EN 771-3, they consist of expanded clay aggregates and a mixture of other naturally occurring raw materials and cement. The clay aggregate is produced from carefully selected clays, which are bloated through heat expansion to create a low density, porous aggregate with numerous cavities. This makes Fibo 850 incredibly light and thermally efficient.

Features and benefits:

Provides a high level of thermal insulation, reducing the amount of additional insulation required after installation.
Lightweight, easy to handle, and quick to lay.
Loadbearing.
Provides a high level of fire protection (Class A1).
For use internally and externally, above and below ground.
Provides a strong background for direct application of plasters and renders (no bonding agents required).
Fixings will be held securely by the block (and can be nailed in directly).
Certification to BES 6001 V4.0 will allow credits to be gained under environmental assessment schemes such as BREEAM.
BSI Kitemarked to BS EN 771-3.
